If Lua represents a string as a contiguous sequence of bytes then an
"excerpt" of the right size (4 bytes, say) would contain the same byte
values as a machine integer, so there wouldn't be a problem from the C
point of view. I see what you mean, though - we shouldn't rely on a
particular implementation of a string (they might use rope structures or
something in Lua 6). There would need to be routines in the Lua C API to
retrieve the raw byte sequence from a string as an integer, float or
whatever.
